ISL32172EFBZ

Overview

The ISL32172EFBZ is a quad RS-422 driver manufactured by Renesas Electronics Corporation, designed for high-speed serial communication. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 32 Mb/s. The device features four drivers with no integrated receivers, drawing a typical operating supply current of 800 uA. It provides robust protection against electrostatic discharge, rated at 15 kV. The component is housed in a 16-lead Narrow SOIC package and is qualified for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides four independent differential drivers compliant with RS-422 standards for reliable data transmission.
• Incorporates enhanced ESD protection capabilities rated at 15 kV to safeguard connected circuitry.
• Operates efficiently with low quiescent current consumption suitable for power-sensitive applications.

Applications

• Industrial control systems requiring robust serial communication interfaces
• Data acquisition networks utilizing RS-422 protocols
• Automotive electronics operating under extreme temperature conditions

Procurement Notes

Verify the specific ordering suffix BZ to confirm the tube packaging format, as suffixes define physical shipping units rather than electrical function. Confirm availability status, as this component may be subject to end-of-life restrictions or limited distribution channels. Ensure compliance with RoHS directives and moisture sensitivity levels before integration into production workflows.

Selection Notes

Select this component when a quad-driver configuration is required without integrated receivers. Compare against the ISL32172EFVZ-T variant if tape-and-reel packaging is preferred over tubes. Verify that the 32 Mb/s speed and 15 kV ESD rating meet the specific environmental and performance requirements of the target application design.

Part Context

This part belongs to the ISL32172E series of RS-422 interface integrated circuits. It shares core electrical specifications with other variants in the family, differing primarily in packaging options such as TSSOP or QFN. The series is engineered for demanding environments where signal integrity and noise immunity are critical for system reliability.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the ISL32172EFVZ-T for identical electrical performance with alternative packaging. Cross-reference with newer Renesas interface families only after verifying pin compatibility and parameter alignment through official datasheets.
